Mercury deposited on land and in drinking water bodies undergoes a crucial transformation – it really is converted by bacteria into methylmercury (CH3Hg), a hugely poisonous natural form.
These emissions lead to the worldwide atmospheric mercury pool and they are a major worry for environmental regulation.
The inorganic salts of mercury are corrosive to the skin, eyes and gastrointestinal tract, and may induce kidney toxicity if ingested.
